Description: brand new and high quality Features: Protective functions: Safe for charging, adjust to deliver the correct current for charging, fully protect the battery from overcharge and over-current, short circuit, etc. Made of high quality environmental-friendly material, durable to use. Simple and small size, easy to install, plug and for play. Protective functions: 1. Input over-current protection When the input current is greater than 2A, the charger will cut off the fuse to avoid internal circuit abnormalities causing fires and other risks. 2. The output current protection Li-ion battery charger for charging current is limited to a range to maintain battery safety and battery life. 3. Short-circuit protection When the charger is improperly used, the charger output current will be 200mA or less to avoid damage. Tips: The current of the constant current constant voltage charger changes with the voltage. If the battery is charged when there is no power, the charging current is maximum at this for time. Specifications: Input: AC110-245V 50/60HZ 0.8A Charging voltage: DC16.8V Measured current 1.6-1.8A Charging Mode: constant current and constant voltage, full self-stop Charge indicator: Red light = charging, green light = fully charged Charger port: DC5.5 x 2.1mm Security protection: OVP/OCP/overload for protection/short-circuit protection Application: Lithium batteries (lithium-ion batteries, lithium polymer batteries) the nominal voltage of the battery pack is 14.4V-16.8V Plug:EU/US(optional) Line Length:90cm/35.43inch(approx.)
